Provided is a bearing arrangement for a wind turbine including a bearing housing and a drive shaft, whereby the drive shaft is arranged within the bearing housing in an axial direction along a longitudinal axis of the bearing housing, the bearing arrangement further including a downwind bearing and an upwind bearing, whereby the downwind bearing and the upwind bearing are arranged between the bearing housing and the drive shaft, wherein the downwind bearing and/or the upwind bearing is a radial fluid bearing including multiple radial bearing pads, whereby each one of the multiple radial bearing pads is attached to one of a multiple radial bearing bodies of the radial fluid bearing and the multiple radial bearing pads are arranged about the drive shaft.

An induction heating device comprising at least one induction coil mounted to a support frame. The support frame is adapted to travel on a surface of an annular metal article to be heated and comprises a wheel set having one or more driven wheels. The support frame is adapted to travel on a side face of the annular metal article and is provided with first guide and second guide elements, which are respectively configured to engage with an outer circumferential surface and an inner circumferential surface of the annular metal article to ensure that the support frame travels on a circular path during use of the device.

A cam follower assembly includes a ball bearing having an outer ring and an inner assembly which includes two or more segments. The inner assembly is disposed in the outer ring with a full complement of balls disposed therebetween. The outer ring and inner assembly each include a race having a gothic arch cross sectional configuration that causes the balls to roll on two portions of each race.

A bearing assembly is for movably coupling first and second members and includes first and second laminated bodies disposed within the second member bore, spaced about a centerline and connected with the first member. The first laminated is formed of alternating, arcuate first elastomeric laminae and arcuate first rigid laminae nested generally about a first central axis, each first rigid lamina having a first radial thickness between inner and outer surfaces. The second laminated body is formed of alternating, arcuate second elastomeric laminae and arcuate second rigid laminae nested generally about a second central axis, each second rigid lamina having a second radial thickness between the rigid lamina inner and outer surfaces. The first radial thickness of the first rigid laminae is substantially greater than the second radial thickness of the second rigid laminae such that the second laminated body has a substantially lesser stiffness than the first laminated body.
